Beaming back down to DS-9 and speaking to Kurland completes this. I don't think they changed over from old DS-9 to new DS-9 in someplace on the completion process.
Had this happen to me, minute left and the finish platform up and vanished as I was coming up to it before I could complete. No DQ from out of bounds, hit every mark for credit.
Pavel has not moved from one beach (25) for over an hour. Fireworks pretty much going off again and again. When trying to move a toon to 25 that needs to do the Pavel line he is not there for that toon. They appear to be well and truly mucked. It would be nice if a zone time clock could be put it once things are no longer…
Had it happen to me, I moved myself and my away team to the far side and waited and it killed itself. Not sure if that will help any of you but it worked for me.
Pretty certain there was a three nacelle dreadnaught in the old Starfleet Technical Manual. Not certain if any of that old stuff is considered canon by the powers that be.
